Application filed July 23, 1912. Serial No. 711,071.

To all whom it may concern:

Be it known that 1, JOHN SABATINO, a citizen of the United States, andresiding at Richmond Hill, in the county of Queens and State of NewYork, have invented certain new and useful Improvements in VibratoryMassage Apparatus, of which the following is a specification, such aswill enable those skilled in the art to which it appertains to make anduse the same.

This invention relates to mechanical vibrator apparatus or devices andespecially to devices of this class wherein the vibratory movements areimparted to and through the hand of the operator for application to apatient or a party being treated, and the object thereof is to providean improved device of this class having means to increase and de creasethe force of the vibrations at the will of the operator, together withimproved means for connecting the device or apparatus with the hand ofthe operator; and with these and other objects in view the inventionconsists in a device or apparatus specified, constructed and operatingas hereinafter described and claimed.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawing forms a part, in which the separate partsof my improvement are designated by suitable reference characters ineach of the views, and in which Figure 1 is a back or plan view of adevice or apparatus of the class specified embodying my invention; Fig.2 a side view thereof; Fig. 3 a section on the line 33 of Fig. 1; Fig. aa section on the line 4-4 of Fig. 2; and, Fig. 5 a section on the line55 of Fig. 3. Fig. 6 is an end elevation of the curved arm Z).

In the practice of my invention, I provide a vibrator a which involves,in its construction, a cylindrical casing of composed of a back sidemember a" and a front side memher a det-achably connected as shown at aand the back side member a is provided axially of the casing with abearing and coupling sleeve a, and the front side member a is providedwith a similar coupling and bearing sleeve a which extends axiallythrough the part a of the casing, and the inner end of which is closedby a threaded cap a and the outer end of which is provided with a necka".

The bore of the coupling and bearing sleeve of is enlarged at the outerend thereof, as shown at a and mounted in said bearing and couplingsleeve is a vibrator shaft 6 the Outer end of which is provided with alongitudinal bore Z) and with a head Z) and the shaft Z) extendspartially and axially through the casing and is provided centrallythereof with a longitudinal slot Z) in which is pivoted a curved arm othe pivot of said arm being at b and the end Z) of said arm is longerthan the other end Z) and is curved as shown and provided with a weightor head Z), and the curve of the end Z) is approximately similar to thecurve of the back side a of the casing a in central axial section ofsaid casing.

Secured to the shaft 6 adjacent to thebearing and coupling sleeve 64 isa collar 0 which prevents the outward movement of said shaft, while thehead 5 thereof prevents its inward movement, and the inner end of theshaft 5 is provided with a reduced extension 0 v Mounted in and movableaxially of the coupling and bearing sleeve 64 is a sleeve bearing (Zprovided at its outer end with a cam head (Z and at its inner end with asleeve (Z to receive the inner end of the shaft Z), and in which saidshaft Z) is free to turn. The sleeve (Z is longitudinally movable on theshaft Z), and the central portion of the bearing (Z is provided with alongitudinal bore (Z adapted to receive the extension 0 of said shaftZ).

Placed in the inner end of the coupling and bearing sleeve 64? is aspiral spring 6 which bears on the cap a of said bearing and couplingsleeve and on the cam head (Z of the bearing (Z and normally serves toforce said bearing outwardly, and passing through the neck a of thecoupling and bearing sleeve 6& is a screw f, the inner end of which isprovided within said sleeve with a cam head f which corresponds with andoperates in connection with the cam head (Z of the bearing (Z, and saidscrew is provided at its outer end with a head f and also with a. locknut f which operates in connection with the neck a of the sleeve Inpractice, a flexible driving shaft 9 having an insulating covering 9 andinclosed by aflexible protection 9 is coupled in connection with thevibrator shaft b within the coupling and bearing sleeve a, as shown atg" in Fig. 1, the bore Z) in the end of the shaft 5 facilitating thisoperation, but this connection of the driving shaft g with the vibratorshaft 6 may be made in any de sired manner and forms no part of myinvention.

In the operation of the device the vibrator shaft 5 is rapidly rotatedby means of the shaft 9 in the usual manner, and this derstood, byturning the screw 7. When this screw is turned in one direction the head6Z3 of the shaft (Z will be forced inwardly and will strike the end 5 ofthe arm. o and force said arm into the position shown in dotted lines inFig. 3, in which position the end 6 thereof will be close to the axialline of the casing a and the force of the vibrations will be much lessthan when said arm is in the position shown in full lines, the end 6thereof being farther away from the axial line of the casing and thusserving to increase the force of the vibrations, and by turning thescrew f in the opposite direction the arm 6 will return or be returnedto the position shown in full lines and the force of the vibrations willbe increased.

The bearing d is capable of longitudinal movement, as shown anddescribed, but is not capable of rotary movement, the cam head (Zthereof being provided with a tooth or projection (Z movable in thegroove d: in the coupling and bearing sleeve as clearly shown in Figs. 3and 5, and while the sleeve (Z at the inner end of the bearing (Z.formsI a bearing for the corresponding end of the shaft Z), said sleeve alsoserves, and its principal function is, to regulate the position of thearm 6 so as to increase or decrease the force of the vibration producedby the rotation of the shaft 6. I also provide my vibrator with a handattaching device it, in the construction of which, I employ a plate h ofthe general form shown in Figs. 1, 2, 3 and 4t, and the back of which isprovided centrally thereof with a standard 72, the end of which isprovided with an opening 71, whereby it may be slipped on over the outerend of the coupling and bearing sleeve a and fitted to an enlargement72,

thereof, and said end of the standard it? isv provided with a set screwit whereby it may be secured in position, as shown in Figs. 1, 2 and 3.The end portion 7L7 of the plate h? is wider than the end portion itthereof, in the form of construction shown, and is provided adjacent toits opposite side edges with parallel slots 2' and the end;

portion 7b8 is provided with corresponding parallel slots 2 and thefront side edge of the plate 71 is provided with ears and f and passedthrough the ear j is a shaft 7' one end of which is pivoted in the earf, as shown at 7", and the other end of which is provided with a milledhead j by which it may be rotated. The shaft j is provided centrallythereof with a ratchet wheel 7' and the standard h is provided with earsy between which is pivoted a spring operated pawl 7' which operates inconnection with the ratchet wheel 7' and is provided with an upwardlydirected handle or thumb and finger piece j by which it may be forcedout of connection with said ratchet wheel. My improved hand attachingdevice also involves two straps 7a and m, and corresponding end portionsof these straps are passed through the slots 2' and 2' in the front edgeportion of the plate 71?, and connected with the shaft j while the otherend portions of said straps are passed through the slots 2' and 2' inthe back edge portion of the plate 7L and are connected with said plateby means of buckle devices a, and by means of these different endattachments for the straps 7c and m said straps may be adjusted at bothends as will be readily understood.

The buckle devices a consist of raised keepers a mounted 011 the plate7L rearwardly of the slots i and 2' in the back edge portion of saidplate and rods a mounted on said plate rearwardly of said keepers a andprovided with tongues or prongs n which are adapted to be passed throughthe ends of said straps, and when put under strain the tongues or prongsa rest on the keepers 11?.

In practice, the fingers of the hand are passed through the strap m,asshown at 0, in Fig. 2, and the second and third fingers are passedthrough the strap as indicated at 0 in said figure, and the said strapsmay be tightened around the fingers by turning the shaft 7' in theproper direction, or this may be accomplished by releasing the pawl 7'from the ratchet j and employing the buckle devices a, but theadjustment of the straps 7c and m may best be effected by means of theshaft j I also provide the plate k with transverse pads 79 and p whichare secured to the underside thereof in the plane of the straps 7c and mand which bear on the backs of the fingers of the hand, as shown in Fig.2, and these pads 39 and 70 may consist of any suitable material and maybe connected with the plate h in any desired manner, and the head f ofthe screw f is provided with a pointer r and the end of the sleeve awith scale marks r in connection with which the point r operates,

this will facilitate the manipulation of the It will be observed thatthe standard k is arranged diagonally on the plate h and the axis of thecasing a is also diagonal of the plate k and the object of thisarrangement of said parts is to hold the flexible shaft 9 out of contactwith the arm of the operator, when the device is in use.

The operation or use of my improved vibratory device will be the same asothers of its class, and this operation will be readily understood bythose familiar with this class of devices.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent, is
